Suggested discussion matters:

1. Describe the geographical features of the mangrove stand

2. Discuss the effects of water quality on the mangrove communities and vice versa

3. Study the interactions of mangrove flora and fauna.

4. Compare the diversity of mangrove flora and associates inside and outside Marine Parks

5. Limitations and improvements of the field study
